This is the second part of a new series about KNX IoT. The series will explain what it is, how it works, and will give practical advice on how to start benefiting from KNX IoT.

As we have established in the previous entry of this series of articles, KNX IoT is a logical additional to the widely established KNX ecosystem. It combines everything that makes KNX so robust, flexible and familiar to installers and architects, with new capabilities brought on by the utilization of IPv6 networking.

Using IPv6 means that KNX installations can leverage existing IP-networking infrastructure in a building, such as Ethernet or Wi-Fi, while also supporting the deployment of new IP-based networks where needed. This provides greater flexibility for both new installations and retrofit applications, enabling wired, wireless, and mesh networking technologies — including Ethernet, Wi-Fi, and Thread — to be used according to the specific requirements of the project. And because IP is the foundation of the internet and networked devices, it offers seamless integration with the cloud, enabling new applications and easy integration with a wide array of services.

This is the first part of a new series about KNX IoT. The series will explain what it is, how it works, and will give practical advice on how to start benefiting from KNX IoT.

They say, “never change a winning team”. After all, if something is working, why change it? The same could be said about the leading smart home and smart building platform, KNX. For nearly 4 decades, KNX has been the preferred technology solution for system architects, installers and end-users alike.

The reasons for that are easy to sum up. KNX is a mature ecosystem, supported by hundreds of product makers, leading to a huge number of products to choose from when planning and constructing an installation. It uses the well-established ETS installation and commissioning software, giving installers all the power they need to configure their installations exactly according to their wishes. And KNX is based on a well-tested and trusted technological basis, ensuring high performance and security throughout the entire chain.

The KNX IoT Environment sensor measures periodically the air quality. It can be used in conjunction with a KNX IoT hub running an MQTT proxy. Together it makes up a system that can cover a large area and the measurements can be conveyed over MQTT and stored at a different location.

The video shows how easy it is setup the system and how to access the data remotely. It contains the following information:

• Using the KNX IoT Environment Sensor with ETS
• Using the MQTT proxy running on the KNX IoT Hub with ETS
• Showing the measurements in ETS group monitor
• Showing the measurements on the (MQTT) dashboard, which can be accessed anywhere in the world.

In the video below, KNX IoT Devices are commissioned on Thread and KNX using an QR scanner.

The video shows the steps to commission:

• Commissioning the Device on Thread (e.g. making it part of the thread network)
• Commissioning the Device using ETS: scanning the QR info and downloading the configuration

These demos can be downloaded to the development board and used with ETS.

Demo applications for the Development board can be found here. The following demos are available:

• Colour Actuator RGB Manual
• Relay Actuator Manual
• Room Temperature Sensor Manual

These demos need additional hardware as described in the corresponding manuals.

In the video below, a setup is used that contains TP devices and IoT devices. To be more exact, on each side a button and an actuator are configured.

The configuration contains that the actuators sends feedback to the buttons.

The network/KNX topology contains an TP section and an IoT section as follows:

This setup is then configured by means of ETS 6, showing the downloading and interoperability of the TP and IoT devices in the following video:

In the seventh of this series of articles on KNX IoT, Bruno Johnson and Wouter van der Beek explain the open source KNX IoT Stack.

If you are using devices communicating over Thread, then you might want to know how good the link quality is of the used communication.

In this video the LQI and RSSI metrics are explained, also the video explains how to obtain those values by using Cascoda’ Sniffer.

If you are developing devices running on Thread, then you can use Cascoda’s packet sniffer to see all the traffic in the air.

The online documentation on how to use the Sniffer is available on GitHub.

However we also made a video that demonstrates the following steps:

• Starting Wireshark, including selecting the Thread channel
• Decrypt Thread network communication (since communication over Thread is always secure)
• Showing IEEE 802.15.4 packets, Thread MLE communication
• Showing CoAP & mDNS traffic
• Decrypt KNX OSCORE messaging
• Showing & explaining the KNX s-mode messages
